feat(api): add setCachePolicy to CardActionType

[Copilot]

setCachePolicy was missing from the CardActionType union, making it impossible to disable Teams' default 30-minute link unfurling cache in a type-safe way.

Changes

• packages/api/src/models/card/card-action.ts
  • Added 'setCachePolicy' to the CardActionType union
  • Corrected the JSDoc on CardAction.type to match the actual union members (removed stale messageBack/openApp entries that were never in the type)

Usage

suggestedActions: {
  actions: [
    {
      type: 'setCachePolicy',          // previously a type error
      title: '',
      value: '{"type":"no-cache"}'
    }
  ]
}

See Teams link unfurling cache docs for context.

Adds missing setCachePolicy to the CardActionType union so consumers can disable Teams’ default link unfurling cache in a type-safe way, and aligns the CardAction.type JSDoc with the actual allowed values.

Changes:

• Added 'setCachePolicy' to CardActionType
• Updated CardAction.type JSDoc to remove stale values and include setCachePolicy
